`- ROLLER-SKATE.

g JoIN lV. MARTRANO, citizens of the United States of America, residingat New Haven, inthe county of-Fayette and State of Penn- Sylvania, haveinventedl certain new and useful 1m rovements in Roller-Skates, of whichthe fo owing is a specification, reference being-had therein totheaccompanying drawin roller skates, and the invention has forits primaryobject to provide a novel two-wheel all-bearing skate.

`Another object of this invention is to roc vide a simple andinexpensive roller s ate vthat can beV easily adjusted to fit upon shoestion, combination and .arrangement of partsv of various sizes.

With the above and other objects in view,

the invention consists inv the novel construcl'-rto'be hereinafter morefully described and then specifically pointed out in the appendedclaims.

In the drawin s, Figure 1 is a longitudinal sectional view ok the skate,partly in eleva tion, Fig. 2 is a horizontal sectional view of theskate, illustrating a bottom plan ofthe body of the skate, and Fig. 3 isa cross sectional view of the skate partly in elevation.

In the accompanying drawings, 1 designates a sole plate having acontracted depending end 2. 3 rde signates a heel plate aving acontracted depending end 4. The ends 2 and 4. are connected together bya conventional form of turn buckle 5 and screw i 6, said screws beingretained in the depending ends 2 vand 4 of the pla-tes 1 and 3, by nuts7. l

The plates 1 and 3 are provided with Wardly extending lugs 8 forengaging edges ofthe sole and heel of a boot or shoe and thus clam theskate thereto and are provided with epending headed rivets 9 by which aplate is connected to the plates 1 and 3. The connecting plate isprovided with a central contracted and lcounter-sunk'portion 1 0, whileits ends'are slotted as at 11, to receive the Shanks` of the headedrivets 9.

Lv ypending bearings 12,l which are riveted or 'jpotherwise securedltosaid connecting plate. 'I the bearing 12 are mounted axles 14 hav- Theconnecting plate is provided with de- Speciflcaton of Letters Patent. I

ing threaded ends 15 for nuts 16and 1&7, the I nuts 16 being locatedupon the inner sides of' the bearings, while the nuts 17 are locatedupon the outer sides of said bearings. These nuts are adapted to firmlywithin the\-bearings. l

Upon eachy axle is revolubly\ mounted a wheel 18 having a solid rubbertire 19. Each wheel has its sides recessed for ball bearings 20, theseball bearings vbeing retained within the recessesof the wheel, bythreaded heads 21, which are screwed inthe recesses of said wheel by aSpanner wrench (not shown) or similar instrument, prior to the 'axles 14of said wheels being placed in the bearings In providing a rubber tiredwheelfor roller skates, We dispense with the noise incurred by theroller skates in action, also preventing sliding or skidding when askater 1s rounding a curve.`

Our improved roller skate also permits of more graceful skating andfigures being described which are impossible with a four? wheel rollerskate.

We do not care to confine ourselves tothe manner of fastening the skateupon a shoe, as straps or similar devices. can be used. It is thoughtthat the manner of adjusting sole and heel plates lto fit various sizesof shoes will be understood.

Having now described our invention what we claim as' new, is

. l A roller skate embodying a sole'plate and i a heel plate each havinga dependlng end, a screw mounted in s aid de ending ends for WM. S.YAND,
